GUSTAF ELLSTROM, OF FITCHBURG, MASSACHUSETTS, ASSIGNOR TO MARY E. JOHNSON, OF FlTOHBURG, MASSACHUSETTS, EXEOUTRIX OF IVER JOHNSON, DECEASED.

Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed, August 10,1904. Serial No. 220,201.

To all whom it may concern.-

Be it known that 1, GUsTAF ELLSTROM, acitizen of the United States, residing at Fitchburg, in the county of Worcester and State of Massachusetts, have invented a new and useful Extractor or Ejector Mechanism for Breech- Loading Firearms, of which the following is a specification.

This invention relates to a construction for removing the shells from the barrel of a breech-loading firearm.

A mechanism constructed according to this invention has been especially designed for use in breech-loading firearms of the breakdown type.

The object of this invention is to provide a strong, simple, and efficient construction which may be adjusted either to throw the shells back completely out of the barrel when an ejector action is desired or which may be adjusted to start and move the shells back to a slight extent only when an extractor action is desired.

To this end this invention consists of the extractor or ejector mechanism and of the combinations of parts therewith, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a side view, partly broken away, of sufiicient parts of a gun to illustrate the application of this invention thereto. Figs. 2 and 3 are similar views showing the parts in diflerent relative positions. Fig. 4 is an enlarged View of the barrel, partly in section, showing the parts adjusted to provide for an ejector action. Fig. 5 is a similar view showing the parts in different relative positions. Fig. 6 is a view similar to Fig. 1, showing the parts adjusted to produce an extractor action. Fig. 7 is a detail view of the plunger. Fig. 8 isa detail view of the setting-cam for holding the parts in positionto produce either an ejector action or an extractor action, as desired. Fig. 9 is a detail view of the catch which cooperates with the plunger to produce an ejector action, and Fig. 10 is a detail view of the locking-bolt for the barrel.

In the use of breech-loading firearms, particularly in the use of breech-loading firearms of the breakdown type, some persons desire to have the shells powerfully thrown back out ofthebarrelwhenever thegunisopened,so that the empty shell will fly out without being removed by the fingers, while other persons prefer to have the gun operated with what is known as extractor actionthat is, to operate so as to start the shells back out of the barrel for a short distance only, the shells then being taken out with the fingers.

To provide for throwing the shells completely out of the barrel, a number of devices have been used which have become known as Y ejectors, while for starting the shells back part Way out of the barrel constructions have been employed which are known as extractors. The especial object of this invention is to provide a gun with simple and efiicientmeans of adjustment. so that either an extractor action or an ejector action can be secured, as desired.

Referring to the accompanying drawings and in detail, a gun embodying this invention as herein illustrated comprises the gun-frame F. Pivotally mounted on a pinf in the frame F is the barrel B, and extending down from the under side of the barrel B is the barrellug or projection L.

Mounted in the gun-frame F is the usual hammer H and other parts of the firing mechanism, which need not be herein shown or described at length.

The parts as thus far referred to may be of the ordinary or any approved construction.

Mounted in the barrel-lug, as shown most clearly in Figs. 4 to 7, is an ejector or extractor plunger 10, having a shell-engaging head 11. At its inner end the plunger 10 is engaged by a powerful spring 12, and the extent of motion of the plunger is limited by a pin 20. Cooperating with the plunger 10 is a catch or detent 13. The catch 13 is intended to cooperate with the plunger, so as to restrain and hold the same back and to thereafter release the plunger with a snap when the gun is completely opened and an ejector action is desired. Extending from the side of the catch 13 is a pin 14, which engages the upper side or a recess or channel in the gunframe, as shown in Fig. 2. Near one end the catch 13 is provided with a notch or slot 15, and extending through the notch or slot 15 is a setting-piece 16. The setting-piece 16 is provided near its center with an operatingcam section 18 and is also provided at one end with a screw-driver slot 17, so that the setting-piece 16 may be turned to permit the catch 13 to rise up into engagement with the plunger 10, as shown in Fig. 2. and which may also be turned to hold the catch down in lnoperative position, as shown in Fig. 6.

IV hen the parts are adjusted to the position shown in Fig. 4:, an ejector is secured, for example, as illustrated in the first sheet of drawings that is to say, when the gun is opened, as shown in Fig. 2, the catch 13 will serve to restrain the plunger 10 and will only release the same when the gun is fully opened, as shown in Fig. 3, and this action then permits the plunger to move back under the full force of its spring and to throw the shell completely out of the barrel. On the otherhand, when the parts are in the position illustrated in Fig. 6 when the gun is opened the head of the plunger will slide up in contact with the recoil-plate of the gun-frame, and this will produce an extractor action, throwing the shell only part way out of the barrel.

In Fig. 10 I have shown theform of barrel-locking bolt which I preferably employ. As herein illustrated, the locking-bolt is made in the form of a frame 19, consisting of sides and an end piece, and' the locking-bolt is mounted in the barrel lug or rib. It is to be understood, however, that in this application for patent I do not claim the particular'form of locking-bolt for the barrel which I have herein shown and described, as this subjectmatter is claimed in a companion application for patent executed by me on even dateherewith.

I am aware that numerous changes may be made in applying my invention to firearms without departing from the scope-of my invention as expressed in the claims. I do not wish, therefore, tobe limited to the construction I have herein shown and described; but

What I do claim, and desire to secure by Letters Patent of the United States, is-

1. In a breakdown gun, the combination of the spring-pressed plunger, a catch arranged to engage the plunger and to hold it against the tension of the spring when an ejector action is required, and a releasing-stud mounted in and swinging with the barrel-lug for holding the catch out of operation to produce extractor action, and comprising cylindrical sections on which the stud is journaled, and an intermediate cam-section which may be turned to engage the catch.

2; In a breakdown gun, the combination of the barrel lug, a spring pressed plunger mounted therein, a catch pivotally mounted in a slot in the barrel-lug and cooperating with the plunger when ejector action is desired, and means for holding thecatch out of operation to produce extractor action, consisting of a stud having cylindrical end sections journaled in the barrel-lug, and an intermediate cam-section which may be turned into engagement with the catch between the pivot of said catch and its hooked end which engages the plunger said catch being mounted in and swinging with the barrel-lug.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
